As someone who lived directly across the river from the Bohemian Grove for about a decade, I can tell you with certainty that the only thing he was right about is that it exists and its members are wealthy. There's nothing secret about the existence or timing of the gatherings, as they're discussed in the local paper. Jobs are advertised for caterers and cleanup crews. The people hired always return, just like any other summer camp type job.
This is a great point -- where can we find some INDEPENDENT FACT CHECKERS that happen to have the same political bias as me to dispute the above? I'm extremely uncomfortable that people have different opinions here.
